@nebulon Yes I know but I think it's a kind of "dirty intregation" regarding how much you have implemented Amazon/DigitalOcean S3 ... And I'm probably not the only one that need a backup in French Infrastructures.

@girish Hum, So bad because it's totally functionnal for me ... I don't know if there is some limitations for others countries.

To enable it, you need an account, then a tenant on the Openstack Part of OVH.
You'r tutorial is quite intresting for one part but in case of failing backup (OVH unavailabled by exemple, that implied that we need to check on the server manually and not directly on the cloudron interface with swift/rsync compatibilities. But I can undestand that not easy to implement their solution..
